Performance and Characteristics

  • 1. PR4250 is a polysaccharide plant that can be decomposed by natural susceptible organisms and is harmless to the environment. The prepared paste has good stability and can be kept for several days under normal conditions.

  • 2. Has good rheology, good brightness and permeability.

  • 3. The printing outline is clear, the color is high, and it is easy to be detached and has excellent hand feeling.

  • 4. Has good chemical resistance stability, such as acid (citric acid, tartaric acid), reducing agent (stannous chloride).




Suitable for polyester, polyamide fiber, polypropylene fiber, disperse dyes for direct printing thickening and burnt thickening, also compatible with textile printing and dyeing thickener (mixed use). Can meet the requirements of flat screen, rotary screen, roller dyeing machine.


Recommended Process

1. Process prescription: the original paste is equipped:

Disperse printing paste PR4250 6%

Water or other94%

Synthesis 100%

Note: PR4250 is slowly dissolved in cold water according to the required amount, and dissolved and stirred to avoid agglomeration. Stirring is continued for at least 10min. The paste can be placed for one night to facilitate maximum expansion. If hot water (about 70 ° C) is used, the dissolution and expansion can be accelerated. Add organic acid, adjust the pH of the stock paste to 5, according to the viscosity of the printing paste, take 30%-65% of the appropriate amount of the reserve paste to prepare the color paste.

2. Process: Disperse printing paste preparation → rotary screen or flat screen printing → drying → steaming fixation (180-185 ° C, 6-8 min) → water washing.

The specific process should be adjusted by the user as appropriate.

  • What is textile thickener?

    Thickeners used in textile printing are high molecular weight viscous compounds gave a sticky paste with water, which impart stickiness and plasticity to the printing paste. These thickeners facilitate to preserve the design outlines without spreading even under high pressure.

  • Why thickener is used in printing?

    Thickeners impart adhesivity and plasticity to the printing paste which can be applied on to the fabric without spreading and hold- ing the dye molecule at the desired place until the transfer of dye into the fabric and its fixation are complete.

  • What are chemical thickeners?

    Thickening agents, or thickeners, is the term applied to substances which increase the viscosity of a solution or liquid/solid mixture without substantially modifying its other properties; although most frequently applied to foods where the target property is taste, the term also is applicable to paints, inks, ...

  • What are the two main types of thickeners?

    There are two main types of thickening agent: starch-based (typically modified maize starch) and gum-based.
